Description

BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an optical disk reading device, and more particularly to the optical disk reading device with an adjustable positioning element that can constrain and adjust guide rods efficiently.
2. Description of the Prior Art
Optical disk drives such as CD-ROM drives have been widely used in multimedia computer system, and more particularly for desktop computers. Most computer manufacturers regard the CD-ROM drives as the standard equipment shipped with their product. At present, the reading speed of optical disk drives have increased significantly with the development of optical data storage medium technology. However, the price of every optical disk drive is significantly lowered in recent years. Thus, for disk drives manufacturers, how to reduce the cost of assembly and key components is a challenge.
FIG. 1 shows an optical disk reading assembly 1 a of a conventional optical disk reading device.
As shown in FIG. 1, the disk reading assembly 1 a is embodied in the conventional CD-ROM drive. The disk reading assembly 1 a is provided with a chassis 10 a, a disk rotating module 20 a, a disk reading module 30 a, and two guide rods 40 a. The disk reading module 30 a is slidably mounted on two guide rods 40 a. The two ends of each guide rod 40 a must be respectively constrained by two holding pieces 50 a fastened by screws 60 a on the chassis 10 a. If we would like to make sure the optical disk drive can read/write data accurately, then a tilt angle of the disk reading module 30 a must be adjusted precisely. In this regard, the disk reading module 30 a fails to do read/write operation accurately if the reading module 30 a cannot receive the reflective laser beam from the optical disk because of an inaccurate tilt angle. Further, when an assembly worker adjusts the tilt angle of the disk reading module 30 a, the assembly worker must fasten the two guide rods 40 a by the four screws 60 a beforehand. However, until the desirable tilt angle of the disk reading module 30 a is determined, the two guide rods 40 a are fixedly secured by the four screws 60 a. If the assembly worker wants to adjust two guide rods 40 a again, he must loose four screws and does the above procedure again. In prior art, the determination of tilt angle of the disk reading module 30 a is tedious and time-consuming. Finally, the disk reading module 30 a can slide along the guide rods 40 a to read the data stored in the CD-ROM optical disk (not shown) that is placed on the disk rotating module 20 a after the tilt angle is determined.
The optical disk reading assembly 1 a of a conventional CD-ROM disk drive has the following disadvantages:
1. A plurality of holding pieces 50 a are necessary to fasten the ends of two guide rods 40 a, which results in increase of manufacturing cost, and
2. The additional holding pieces 50 a require more assembly workers to assemble. Even worse, because the holding pieces 50 a are thin and light, it is difficult and time-consuming for assembly workers to assemble the holding pieces 50 a to the chassis 10 a until the tilt angle is determined.
As mentioned, the disadvantages of the conventional optical disk unit must be overcome. Thus, there remains a need for an adjusting device that can constrain and adjust two guide rods with much less manufacturing cycle time and costs.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an optical reading with an adjusting device that can constrain and adjust guide rods efficiently.
It is another object of the present invention to provide a disk reading assembly with an adjusting device that can adjust the guide rods with three adjusting screws and resilience of the adjusting device. The present invention requires fewer components, thereby causing cost of manufacture to be decreased and complexity to be reduced.
According to the purposes of the present invention, a disk reading assembly has a chassis, a first guide rod, a second guide rod, an adjustable positioning element, a clamping plate, a disk rotating module and a disk reading module. Each end of the first guide rod and the second guide rod are respectively disposed on the chassis. One end of the second guide rod is fixedly secured to the chassis. The adjustable positioning element constrains two ends of the first guide rod and the other end of the second guide rod respectively. The clamping plate is used to restrain a portion of the adjustable positioning element on the chassis. Therefore, two guide rods can be mounted and adjustable on the chassis by the three adjusting screws and resilience of the adjustable positioning element.

FIGS. 2-4 illustrates an optical disk reading assembly 1 according to embodiment of the present invention. Also, FIG. 3 best illustrates the interconnections of the various components of the optical disk reading assembly 1.
Referring to FIGS. 2 and 3, the optical disk reading assembly 1 according to the present invention has a chassis 10, a first guide rod 20, a second guide rod 30, an adjustable positioning element 40, a clamping plate 50, a disk rotating module 60 and a disk reading module 70. The chassis 10 has a central hole 2, a front folded sidewall 21, a right folded sidewall 22, a rear folded sidewall 23 and a left folded sidewall 24. The chassis 10 also has a right support 141 positioned near the right sidewall 22, a left support 142 positioned near the left folded sidewall 24 and a front support 143 positioned adjacent the disk rotating module 60. In addition, the chassis 10 includes a fixing mount 13 positioned adjacent the disk rotating module 60 and a hook 15 positioned near the front support 143.
A hole 12 is defined in the front folded sidewall 21, and a groove 11 is defined in the left folded sidewall 24. Screw holes 161, 162 and 163 are provided on the chassis 10 and near the right support 141, the left support 142 and the front support 143 respectively. Further, screw holes 514 and 515 are also defined on the chassis and adjacent the right folded sidewall 22 and the left folded sidewall 24 respectively.
Referring to FIG. 3, the disk reading module 70 is slidably mounted on the first guide rod 20 and the second guide rod 30. One end of the second guide rod 30 is fitted in the fixing mount 13, and the right support 141 is adapted to receive the other end of the second guide rod 30. Similarly, the left support 142 and the front support 143 are adapted to receive both ends of the first guide rod 20.
The adjustable positioning element 40 is of metallic material and has a plurality of line segments. Alternatively, the adjustable positioning element 40 can consist of several plate segments. Further, the adjustable positioning element 40 includes a first constraining portion 41, a second constraining portion 42 and a third constraining portions 46.
In addition to the above, referring to FIG. 3, the clamping plate 50 is substantially shaped as an inverted “U”, and two holes 513 and 516 are provided thereon.
To implement the adjustable positioning element 40 to the optical disk reading assembly 1, both ends of the adjustable positioning element 40 are fitted to the hole 12 of the front folded sidewall 21 and the groove 11 of the left folded sidewall 24, respectively. Then, the first constraining portion 41, the second constraining portion 42 and the third constraining portions 46 contact and constrain one end of the second guide rod 30 and two ends of the first guide rod 20 respectively. A right-angled segment 47 of the adjustable positioning element 40 is hooked to the hook 15, and the protruding portion 44 is fitted to the groove 11 of the left folded sidewall 24. In this regard, the adjustable positioning element 40 functions to secure the first guide rod 20 and the second guide rod 30 to the chassis 10 at the same time.
Referring to FIG. 3, two screws 511 and 512 extend through the holes 513 and 516 to threadly engage with the clamping plate 50 and the chassis 10. In this manner, the adjustable positioning element 40 can be fixed on the chassis 10 by the clamping plate 50, as shown in FIG. 4.
FIG. 5 illustrates the cross-sectional view taken along the line A—A and viewed from the rear folded sidewall 23. FIG. 6 illustrates the cross-sectional view taken along the line B—B and viewed from the front folded sidewall 21. When the assembly procedure of the adjustable positioning element 40 is complete, the tilt angle of the disk reading module 70 must be determined. Before the determination of tilt angle begins, the optical disk reading assembly 1 must be placed on a tilt measurement machine (not shown). As described above, the adjusting screws 171, 172 and 173 can be adjusted if necessary.
Referring to the FIGS. 3 and 5, the adjusting screws 171 and 172 thread through the screw holes 161 and 162 and are used to adjust the first guide rod 20 and the second guide rod 30. When either adjusting screw 171 or 172 further is threaded into the screw holes 161 or 162, the optical plane defined by the first guide rod 20 and the second guide rod 30 is changed.
Similarly, referring to FIGS. 3 and 6, the adjusting screw 173 threads through the screw hole 163 and is used to adjust the first guide rod 20 and the second guide rod 30. When the adjusting screw 173 further is threaded into the screw hole 163, the optical plane defined by the first guide rod 20 and the second guide rod 30 is changed. Once the tilt angle of the disk reading module 70 is determined, the assembly procedure of the optical disk reading assembly 1 is complete.
The advantage of the present invention is that the adjustable positioning element 40 constrains the first guide rod 20 and the second guide rod 30. By adjusting three adjusting screws 171, 172 and 173, the tilt angle of the disk reading module 70 can be easily determined. Therefore, the disk reading assembly with the adjustable positioning element that can adjust and constrain the guide rods with three adjusting screws and resilience of the adjusting device.
